net_maxfilesize

"The server is running my map fine but clients get 'missing BSP' message??"

Configuring

You will need to edit your server.cfg file for this. Your server.cfg file should be in your cfg folder. The limit for net_maxfilesize is 64. Setting net_maxfilesize to this value will allow clients to download content which is 64MB or smaller in size.

Alternative

net_maxfilesize only affects slow downloads via the Source Dedicated Server. Consider using a web server instead if possible, which allows much faster downloads. The cvar for this is sv_downloadurl.
